. To allay/"1,0771, t ntay concern,.-

Be it known that we, HENRY STAFFORD GOLLAND, merchant, residing at TheGables, Broad Oak Park, Worsley, and JOHN DEMP- STER WHYTE, engineer,residing at 108 Burlington street, Manchester, in the county ofLancaster, England, subjects of the King of Great Britain and Ireland,have invented certain new and useful Improvements in Spin` for effectingthis described in such prior pat ent Were the provision of an inclinedsurface or guide for each thread, such guides being 2 5 interposed inthe space between the winding faller-wire and the spindles. When theyarn is being wound upon the spindles during the run in of themule-carriage, the yarn guides or inclines are rapidly reciprocated ashort 3o distance, causing each thread to run up and down the surface ofits guide. The threads being thus vibrated are Wound upon the spindlesin widely-pitched spirals, which is termed cross-winding. y Our presentinvention relates to improved means for forming the cop-bottoms and forreciprocating the inclines or yarn-guides.

When commencing the build of the cops upon the spindles, we begin with aminimum 4o traverse of the incline carrier and gradually increase suchtraverse, returning at each stroke to the initial starting-point of theincline carrier. We thus gradually lengthen the stroke of the inclinecarrier until the copbottom is formed, after which the lengthened strokeattained is continued throughout the building of the cops.Greatly-improved results are thus obtained in the formation of thecop-bottom.

shaft c'.

,the slidable part 17 and the attached incline carrier, the pokers ofthe mule raising the slidable part with attached incline carrier toeffect the building of the cops in the manner disclosed in anapplication for patent made by us of even date herewith.

To reciprocate the slide, We provide a lever 18, mounted on a block 19,capable of sliding `iu a slot formed in a bracket 20 and in a slotformed in the lever 18. The slide 12 is con- 7o nected by a stud 21 tothe lever .18, the stud being carried by a block 22, also capable o fsliding to some extent in a slot in the lever 18, so as to compensatefor the curved path described by the upper end of the lever 18 75 whenit is vibrated. The lever- 18 is vibrated bya stud 23, engaging with acam 24, the cam being revolved by a train of gearing 25 from a pinion10, receiving motion from a rack Zon the floor as the mule-carriage runsin and 8o out. The stud 23 is guided and supported by a slide 23*. Thefulcrum or block 19 of the lever 18 is provided with a pendent rod 26,the bent foot 27 of which rests upon a stud 28, carried by a bowl orcollar on the poker- This shaftt' is slowly revolved in the direction ofthe arrow to eect the raising of the pokers to which the yarn-guidecarrier is secured, as explained in our prior application of even dateherewith, and as this shaft 9o c' is slowly revolved the pendent rod 26also slowly falls, thus lowering the slidable block or fulcrum 19 withinthe lever 18 and bracket 20. As the distance from the stud 21 to thefulcrum 19 of the lever is thus lengthened, the 95 throw of the stud 21is gradually increased, correspondingly increasing the traverse of theslide 12, by means of which the incline carrier is actuated. When thecop-bottoms have been formed, an adjustable stud 29, carried by the foot27 of the rod 26, comes into contact with a stop-rod 30 or any otherfixed part of the mule-carriage 31, and thus prevents the furtherdownward movement of the rod 26. The fulcrum 19 of the lever 18 thenremains stationary during the remainder of the build ot' the cops, andthe oscillations of the lever 18 and stud 2l remain constant in theirlength of traverse.

We declare that what We claim is- The means for vibrating theyarn-guides and for effecting a minimum reciprocation of the yarn-guideson the commencement of a cop-bottom and gradually increasing thetraverse of the yarn-guides so that a maximum traverse is attained whenthe cop-bottom is completed and thereafter maintaining such maximumtraverse, said means consisting of a slide 12 with inclined extension15, an incline carrier sliding thereon, a lever 18 having a movablefulcruln 19 for reciprocating the slide, a cam 24 for vibrating thelever 18 a train of gearing 25 for revolving said cam a pinion carriedby the mule-carriage for imparting motion to the gearing a rack Zgearing with said pinion, a pendent rod 26 secured to the movablefulcrum of the lever 18a poker-shaft i and a stud 28 carried by a collaron the poker-shaft z' for supporting the rod 26 and stop-pin 29 to limitthe downward movement of the rod 26 substantially as described.

In testimony whereof We have hereunto set our hands in presence of twowitnesses.
